Metrology-Grade Digital Rockwell Hardness Testing

The QualiRock Digital Series represents the pinnacle of deadweight-type hardness testing, engineered to meet and exceed the rigorous standards of ASTM E-18 and ISO 6508. Available in two configurations—QualiRock-R (Regular) and QualiRock-RS (Twin: Regular & Superficial)—these testers combine the reliability of proven mechanical loading with the precision of advanced digital readout technology.

Designed for both high-volume production floors and precision quality control labs, the QualiRock series features a unique Extended Indenter Nose, allowing for the testing of difficult geometries, such as the internal surfaces of rings (>23mm diameter) and external curves of round bars (>3mm diameter), without requiring complex fixtures.

Ideal Applications

🔥 Heat Treatment Verification
Rapidly verify HRC/HRB values on hardened steel, carburized layers, and tempered components to ensure process control.

⚙️ Gear & Bearing Manufacturing
The protruding nose design enables direct hardness testing on gear teeth and inner bearing races where standard testers cannot reach.

🔩 Thin Wall & Surface Coatings
Use the QualiRock-RS (Twin) model for Superficial scales (15N, 30N, etc.) to accurately test thin sheets and surface-hardened layers without penetration through the substrate.

Key Features & Advantages

✔
Superior Geometry Access: The horizontal protrudent indenter (Extended Nose) allows you to test surfaces that standard testers cannot reach, including internal tubes (Min Ø 23mm).
✔
Advanced Digital Interface: Features a high-definition backlit LCD. Eliminate parallax errors associated with analog dials and reduce operator fatigue.
✔
Intelligent Functions: Includes automatic scale conversion (to Vickers, Brinell, Leeb), Upper/Lower limit alarms for QC pass/fail, and curvature correction for cylinders/spheres.
✔
Data Connectivity: Equipped with an RS-232 interface for data output to PCs or printers, streamlining documentation and quality audits.
✔
High Accuracy & Repeatability: Frame deformation is <0.5% (ASTM requires <1%), ensuring structural rigidity and reliable results even under heavy daily use.
